Peyron Jean Marc, Blanchet Costermans Muriel, Tsevery Jean Marc, Day Eric, Zundel Carina: Air separation comprises use of cryogenic distillation in installation with mixing column and double column, where vaporizer-condenser bath is used as storage to balance demand for oxygen-rich gas. Air Liquide, April 1, 2005: FR2860286-A1 (2 worldwide citation)

The bath of a vaporizer-condenser (5) is used as a means of storage, operating at substantially the same pressure as the base of the low pressure column. If the need for oxygen-enriched gas reduces, the flow of oxygen-enriched liquid taken from the bath reduces. If the need for oxygen-enriched gas i ...
